Letters Patent No. 95,128, dated September 21, 1869.

IMPROVEMENT IN WATCHES.

The' Sbhedule referred to in these Letters Patent and making part of thesame.

To all 'whom 'it may concern Be it known that I, CHARLES S. MosnLEY, ofE1- companyingdrawngs, making part of this specification,

in which- Figure 3 is a view in which the barrel-bridge is removed.

.Figure lis a section,- through red linea: y. Figure 2 is a ont or sideview. 1

The running-parts of the watch are not shown in any ofthe gures.

, The object of my invention is, the exclusion of dust from thewatch-movement.

To enable others skilled'in the art to-Inake and use my improvement, Iproceed to describe its construction and operation.

In the drawings- A represents the pillar-plate, and B, the top plate ofa watch.

These plates are made in the usual manner, except.

That part C which rests upon the top plate is ofthe usual form; but atright angles withv this part C, is a thin piece, c, extending tothepillar-plate, and having a projection, d, which passes over the barrel.

The barrel-bridge (with the additional parts c d attached) is made froma single piece of metal.

The dotted lines (ig.2) indicate the position ofthe ends of c.

It is evident that when the barrel-bridge is constructed as described,that part lettered c (Z, so far as it extends around 'the edge ofthemovement, protects the same from dust.

rIhe protection is rendered complete by the use of two short, thinstrips or ribbons of metal, a a, of such Width as to fit into thegrooves b b', and of' such length as to reach' from the edges of the'part c of the bridge C around far enough to have their ends meet on theopposite side; Y

These strips, or ribbons, may be made of brass, rolled out thin, or ofthe same material that watch# springs are made of, they being made'suliiciently lexble to adapt themselves to the curve of the grooves b b.

These two strips'a a, when thus inserted, together lwith' the projectingportion c of the-bridge C, form a protection, enclosing the works, andexcluding dust and dirt therefrom.

The outer ends of the strips aY a are to be provided with a hole', orprojection, into or against which .to place anyisuitable instrument forremoving the strips, when necessary.

, 'It is obvious that, if preferred, the two strips a a maybe madeinrone piece, instead of two, and used in the same manner. In anyevent-,the ends should fit snugly against the sides of the part c of thebridge G, so as Ato make a tight joint at that point.

I am aware that so-called dust-rings are used;

lbut my device has several advantages over these. It

is more compact, and accomplishes the object more ei'eciively.

Having thus fully described my invention,

. -What I claim as new, and desire to secure by Letters Patent, is asfollows:

1. 'The'combnation of the bridge C, provided with the lip c and thestrips a., when arranged substantially as described. v

2. 4Providing the plates A B with grooves b b', substantially as and forthe purposespspeciied.

3. The metallic strips a a, in combination with the plates A B, havingthe grooves b b', substantially as and for the purposes'specied.
